[0033] The present invention provides an explosion-proof intelligent electric lubrication device.

The thermal overload module includes a thermal overload relay.

[0034] For example, in the accompanying drawings of this embodiment, the number of oil outlets 21 of the lubrication pump 2 is set to 3, and the number of oil supply ports 12 on the box body 1 is set to 4; one of the oil outlets 21 on the lubrication pump 2 can be connected to a tee pipe so that the oil outlet 21 can be connected to two oil outlet pipelines; the oil filling port 11 is connected to the top of the grease cylinder 4 through a pipeline, and when grease needs to be added, the grease is added from the oil filling port 11 to the grease cylinder 4 through a pressurizing device.

[0035] In some embodiments, as Figures 1 to 6 As shown, a partition 13 is provided in the box body 1 , which divides the interior of the box body 1 into a working area 14 and a control area 15 . The lubrication pump 2 and the explosion-proof motor 3 are located in the working area 14 , and the control module 5 and the thermal overload module are located in the control area 15 .

[0036] It should be noted that, by providing a partition 13 in the box body 1 , the control module 5 and the lubrication pump 2 can be separated, so that each area can be easily disassembled and assembled separately.

[0037] In some embodiments, as Figures 1 to 6 As shown, the lubrication pump 2 and each oil outlet pipeline are provided with a pressure sensor, and the pressure sensor is electrically connected to the control module 5; wherein, when the detection value of the pressure sensor is greater than the preset pressure value, the control module 5 controls the alarm module to alarm; the alarm module includes an explosion-proof signal light 6, and the explosion-proof signal light 6 is electrically connected to the control module 5; the explosion-proof signal light 6 is arranged on the top of the box body 1, and the box body 1 has a through hole for the cable to pass through.

[0038] It should be noted that when the detection value of the pressure sensor exceeds the preset pressure value, the control module 5 outputs an alarm signal to the alarm module, thereby causing the alarm module to alarm. At this time, the explosion-proof signal light 6 lights up to remind the operator that an abnormal situation has occurred.

[0039] In some embodiments, as Figures 1 to 6 As shown, the lubrication pump 2 has several connecting protrusions 23, and each connecting protrusion 23 has a connecting rod 24; the top of the grease cylinder 4 has a protrusion 41 corresponding to the connecting protrusions 23 one by one, and the protrusion 41 has a through hole for the connecting rod 24 to pass through; wherein, the protruding end of the connecting rod 24 has an external thread, and the protruding end of the connecting rod 24 is connected to a nut 42 to fix the relative position of the grease cylinder 4 and the lubrication pump 2.

[0040] It should be noted that the connecting protrusion 23 is fixed on the outer casing of the lubrication pump 2, and the protrusion 41 is fixed on the top of the grease cylinder 4; after the grease cylinder 4 is installed on the lubrication pump 2, the top end of the connecting rod 24 can pass through the protrusion 41. At this time, the grease cylinder 4 can be fixed on the lubrication pump 2 by threading the nut 42 with the connecting rod 24.

[0041] In some embodiments, as Figures 1 to 6 As shown, the top of the grease cylinder 4 has an air hole, and the grease cylinder 4 is provided with a filter membrane at the position of the air hole.

[0042] It should be noted that by providing an air vent at the top of the grease cylinder 4 , the air pressure in the grease cylinder 4 can be balanced; and by providing a filter membrane at the position of the air vent, the amount of debris entering the grease cylinder 4 can be reduced.

[0043] In some embodiments, as Figures 1 to 6As shown, the control area 15 in the box body 1 is provided with a display screen 51, and the display screen 51 is electrically connected to the control module 5; the side wall of the box body 1 is provided with a first observation window 16 on the side opposite to the display screen 51; the grease cylinder 4 is made of a light-transmitting material, and the side wall of the box body 1 is provided with a second observation window 17 on the side opposite to the grease cylinder 4, and the side of the second observation window 17 has a plurality of scales 18 arranged along the height direction; wherein, the scale 18 and the projection of the grease cylinder 4 on the vertical plane are positive projections.

The liquid level sensor can detect the grease in the grease barrel 4. When the liquid level in the grease barrel 4 is lower than a preset value, the liquid level sensor can transmit a liquid level signal to the control module. After receiving the liquid level signal, the control module transmits an alarm signal to the explosion-proof signal light 6, at which point the explosion-proof signal light 6 starts to alarm. Through the above-mentioned configuration of the present application, an automatic liquid level alarm can be achieved, which can remind the operator to add grease in time.

[0049] Illustratively, each oil outlet pipeline is provided with a pressure relief valve, and the outlet of the pressure relief valve is connected to a position near the top of the grease cylinder 4 through a pipeline; when the oil supply port is blocked, the pressure in the oil outlet pipeline will increase; after the pressure in the oil outlet pipeline reaches a preset value, the pressure relief valve opens to realize the pressure relief process, thereby preventing the lubrication pump from being damaged due to excessive pressure; through the above-mentioned setting of the present application, the function of overpressure protection can be realized, and when the grease pressure in the pipeline is greater than the preset value, the process of automatic pressure relief can be realized.

[0050] In some embodiments, as Figures 1 to 6 As shown, there is a document placement slot 19 on the side wall of the box body 1; after the operator repairs this application, the maintenance record is recorded on the maintenance file, and then the maintenance is placed in the document placement slot 19; through the above setting, the maintenance file can be better preserved.
